[0003] But there are following deficiencies in the prior art: the current portable tunnel fire-fighting equipment based on municipal water supply, because the depth of the tunnel is too long, only a fire-fighting equipment is installed at a certain distance, so a portable and stretchable fire-fighting nozzle is used to cooperate with the pipeline The extension is carried out, but due to the limitation of the distance, the length of the municipal pressurized water supply is extended, resulting in insufficient internal water flow pressure, which in turn causes the water sprayed by the firefighting equipment to reach the distance.

Embodiment 1
[0026] as attached figure 1 To attach Figure 5 Shown:
[0027] Its structure includes a spray gun head 1, an extension pipe 2, a water flow valve 3, a water supply pipe 4, a reel 5, a rotating shaft 6, and a fixed frame 7. The end of the spray gun head 1 is connected to the flange of the extension pipe 2, and the extension pipe 2. The end is flange-connected with the water supply pipe 4. The water supply pipe 4 is nested and connected with the surface of the take-up reel 5. The center of the take-up reel 5 is movably matched with the rotating shaft 6. The end of the water supply pipe 4 is nested and connected with the water flow valve 3, the water flow valve 3 is in clearance fit with the spray gun head 1, the fixing frame 7 is nested with the top of the water supply pipe 4, and the spray gun head 1 includes a flow Cavity 11, water outlet 12, diffuser 13, connecting pipe sleeve 14, the interior of the flow chamber 11 is in active cooperation with the diffuser 13, the lower ...

[0034] as attached Figure 6 to attach Figure 7 Shown:
[0035] Wherein, the pressurized turntable 134 includes a movable chamber b1, a runner b2, an auxiliary rod b3, a pressurized disk b4, and a collar b5, the center of the movable chamber b1 is nestedly connected with the pressurized disk b4, and the pressurized disk The surface of b4 is movably matched with the runner b2, the center of the runner b2 is nested and fitted with the auxiliary rod b3, the auxiliary rod b3 is welded to the collar b5, and the inside of the collar b5 is clearance-fitted with the runner b2. The runner b2 has a hollow ring shape as a whole, is fixed by the auxiliary rod b3, and moves under the drive of the collar b5, and the booster plate b4 is beneficial to pressurize the water flow in a disguised form when the pressure is insufficient due to too long a distance.
[0036] Wherein, the pressurized disk b4 includes a card slot c1, a swing leaf c2, a rope slider c3, an overflow cavity c4, and a blo...

Abstract
The invention discloses a portable tunnel fire fighting equipment based on municipal water supply. The portable tunnel fire fighting equipment structurally comprises a spray gun head, an extension pipe, a water flow valve, a water supply pipe, a winding disc, a rotating shaft and a fixing frame. The tail end of the spray gun head is connected with the extension pipe through a flange, the tail end of the extension pipe is connected with the water supply pipe through a flange, and the water supply pipe is connected with the surface of the winding disc in a nested mode. The center of the winding disc is movably matched with the rotating shaft, the center of the rotating shaft is connected with the water supply pipe in a nested mode, the tail end of the water supply pipe is connected with the water flow valve in a nested mode, the water flow valve is in clearance fit with the spray gun head, and the fixing frame is matched with the top end of the water supply pipe in a nested mode. The spray gun head comprises a circulation cavity, a water outlet, a diffuser and a pipe connecting sleeve. After a rotary pressurization rotating disc rotates, a swing blade is pressed into a clamping groove while an inner rotating wheel rotates, so that a rope sliding block covers a cavity of a stop block, the stop block is blocked in a disguised mode, the water flow pressure in an overflow cavity is increased, disguised pressurization is effectively conducted under the condition that the distance is too long and the pressure is insufficient, and sufficient water flow pressure is ensured.
Description
technical field [0001] The invention relates to the municipal field, in particular to a portable tunnel fire-fighting equipment based on municipal water supply. Background technique [0002] Municipal water supply is a part of urban public utilities. Through municipal water system planning within the city, the interconnection of water supply within the city is realized. The municipal water supply system is usually composed of water sources and water plants. After water is taken, it is transported to the water plant through water pipes for water quality treatment. The final water is distributed through the water pipe network through pressurization; [0003] But there are following deficiencies in the prior art: the current portable tunnel fire-fighting equipment based on municipal water supply, because the depth of the tunnel is too long, only a fire-fighting equipment is installed at a certain distance, so a portable and stretchable fire-fighting nozzle is used to cooperate ...
